A facile route for the formation of shape-selective ZnO nanoarchitectures with superior photo-catalytic activity

Highly Sensitive and Selective H2S Chemical Sensor Based on ZnO Nanomaterial

ZnO is worth evaluating for chemical sensing due to its outstanding physical and chemical properties. We report the fabrication and study of the gas sensing properties of ZnO nanomaterial for the detection of hydrogen sulfide (H2S). This prepared material exhibited a 7400 gas sensing response when exposed to 30 ppm of H2S in air. In addition, the structure showed a high selectivity towards H2S against other reducing gases. The high sensing performance of the structure was attributed to its nanoscale size, morphology and the disparity in the sensing mechanism between the H2S and other reducing gases. We suggest that the work reported here including the simplicity of device fabrication is a significant step toward the application of ZnO nanomaterials in chemical gas sensing systems for the real-time detection of H2S.

One-pot, template-free syntheses of spherical ZnS nanocrystals using a new S2−source and their photocatalytic study

A facile, one-pot solvothermal method for the syntheses of template-free ZnS NCs (~3–6 nm) using (C₇H₇)S₂as a newin situsource of S²⁻ions without and with the use of MCE-capping agent has been demonstrated. Photocatalytic investigation of the NCs revealed very good activity for degradation of MO under UV light irradiation.
